Zebra and quagga mussels were collected from Lakes Erie and Ontario in 1997 and the soft mussel tissues were analyzed for Ca, Cd, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Se, Sr, V and Zn. No consistent relationships were apparent when comparing element concentrations in soft mussel tissues and mussel type, size range or sampling location. Literature dealing with the absorption of metals by both mussel types is reviewed.

Smelt (Osmerus mordax) were netted from Cayuga Lake in Central New York State and analyzed for mercury concentration. There was no statistical significance (p > 0.05) when attempting to correlate mercury concentration with fish length or weight for either sex.

While appreciable attention has been given to the elemental composition of ashes from municipal solid waste incinerators, relatively little information is available on the elemental content of incinerators burning animal carcasses and medical wastes. In the work reported here, an analytical survey was conducted of the concentration of 22 elements in the ashes of incinerators located at veterinary colleges or animal disease diagnostic laboratories in seven states. With the exception of Zn, the concentrations of most elements were well below those found in ashes from municipal solid waste incinerators.

Brazil nuts (Bertholletia excelsa) natively contain very high concentrations of selenium. Since dietary selenium, including Brazil nuts, have been associated with protection against tumor development in laboratory animal studies, it was of interest to determine the selenium content of the nuts from different nut-growing regions of Brazil. In the work reported, 162 nuts from each of two regions (Acre-Rondonia and Manaus-Belem) were individually analyzed for selenium.
